A synthetic approach toward optically active lycorine: Synthesis of optically active 2-methyllycoranes by radical reaction

A synthesis of optically active 2-methyl-α-lycoranes (2a) and their stereoisomers (2b, b', c) using radical-mediated cyclization is described. The B ring in lycorane was constructed by 5-exo cyclization of (4S, 1″ E)-4-hydroxy (11)-, 4-acetoxy (12)-, 4-be
